10. Press the MENU button for the meter to accept the new value. The
meter then flashes "rd2" .
11. Apply the high input voltage or current for the selected input range (e.g.
apply 9.900 V if you are calibrating 0-10 V range).
To calibrate the entire meter, you only need to calibrate the
following three ranges: 0-10 V, 0-5 V and 4-20 mA.
Range
0-10V
0-5, 1-5V
4-20, 20-4 mA
* Disregard decimal point
12. Change the display to equal the input source (e.g. if you apply
9.900 V for the high input voltage, change the meter reading to "9900").
Press the £/MAX button to change the flashing digit's value (increments
by one) and press the ¢/TARE button to move from one digit to the
next.
13. Press the MENU button once more to save changes. The meter shows
"Stor" and is now calibrated for the selected range.
14. Power off the meter. Remove the S4 jumper (to ensure no accidental
changes). Slide main board back into the case.
